Halfway through Leo XIV's first speech as pope, which he delivered in Italian, he stopped and asked if he might say a few words in Spanish.

Smiling, he continued: "A greeting to all and in particular to my dear Diocese of Chiclayo, in Peru."

The first American pope is a citizen of Peru and has spent much of his life there, travelling between the two countries for decades until 2014, when Pope Francis appointed him bishop of the Chiclayo Diocese in the country's north.

On Thursday, Peruvians rejoiced at the appointment of one of their own to the highest position in the Catholic Church.

Standing near Lima's cathedral shortly after bells rang out in celebration of the appointment, elementary school teacher Isabel Panez said: "For us Peruvians, it is a source of pride that this is a pope who represents our country."

Prevost would often say that he had "come from Chicago to Chiclayo – the only difference is a few letters," Diana Celis, who attended several Masses officiated by the then Bishop Robert Prevost, told the Associated Press news agency.

He reportedly referred to Peru, where around three quarters of people are Catholic, as "mi segunda patria" – my second homeland.

Peru's president, Dina Voluarte, described Pope Leo as Peruvian "by choice and conviction".

"The pope is Peruvian; God loves Peru," she said.
